This Review covers state-of-the-art reconfigurable and tunable optical components and highlights the emergence of a set of materials that offer a new toolkit for tunability and control.
Lithium tantalate (LiTaO3) is heterogeneously integrated with silicon photonics circuits, enabling high modulation speed, reduced bias drift and a high optical damage threshold, while ensuring full compatibility with the existing silicon photonics process design kit.
Mode mixing and mapping with a piece of multimode optical fibre and spatial light modulators creates a bridge between two isolated quantum networks, linking distant nodes with quantum connectivity.
This Review discusses recent advances in sensitized fluorescence emitters for deep-blue organic light-emitting diodes, reviewing progress in molecular design and device performance as well as key remaining challenges.
Optical computing has been limited to vector–matrix multiplications, with matrix–matrix operations requiring wavelength- or time-division multiplexing, reducing energy efficiency and speed. Now, researchers have demonstrated a free-space optical approach that overcomes these limitations, enabling parallel matrix–matrix and tensor–matrix multiplications in a single optical operation.
Modulating an electron beam with a frequency-beating laser enables a free-electron laser to generate high-power, narrowband terahertz pulses that can be continuously tuned from 7.8 to 30.8 terahertz.
This Review discusses recent advances in interlayer engineering for perovskite solar cells, highlighting promising materials and architectures that could improve the stability and efficiency of devices.
From super-resolution endoscopes to multi-photon microscopes, photonic technologies are being translated from laboratory innovations to tools for clinical diagnosis and biological inquiry.
A nanostencil lithography technique enables fabricating arrays of green-emitting OLEDs with pixels as small as 100 nm and an external quantum efficiency of 13.1%.
500,000 heat-related deaths occur each year, according to the World Health Organization. Passive and active photonic-based cooling strategies were discussed at a recent Sydney Radiative Cooling Workshop.
Vitrification of polymer solutions yields ultrasmall fluorescent polymer dots that combine dye-like size with nanoparticle brightness, enabling nanometre-precision live-cell tracking on standard microscopes.
Structured light and photothermal conversion are used to create reconfigurable thermal barriers in a microfluidic device. These virtual barriers can be used to dynamically control fluid flow and microparticle trajectories.
Simultaneous high-bandwidth and high-optoelectronic conversion efficiency in photodiodes is difficult to achieve. Now, researchers have demonstrated waveguide-integrated photodiodes with over 200 GHz bandwidth, 0.81 A/W responsivity and a bandwidth–efficiency product of 133.5 GHz, thus enabling amplifier-free 120 Gbps wireless transmission over 54 m.
Shining intense laser pulses on an electron beam in an electron microscope corrects electron-optical spherical aberration, paving the way to using light to improve electron microscopy imaging.
This Review provides an overview of the progress in quantum structured light, both as single and entangled photon states, with an emphasis on prospective applications in quantum information science such as quantum communication and quantum imaging.
